DOSBox – a free and open-source DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X…
DOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem/XMS/EMS, Tandy/Hercules/CGA/EGA/VGA/VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games…
DOSBox emulates a full x86 pc with sound and DOS. Its main use is to run old DOS games on platforms which don’t have DOS (Windows 7, 8, 8.1 and 10 / Linux / FreeBSD / Mac OS X).
DOSBox emulates the CPU, the sound and graphic cards, and some other stuff, all at the same time. You can overclock DOSBox by using CTRL-F12, but you’ll be limited by the power of your actual CPU. You can see how much free time your true CPU has by various utils (top). Once 100% of your real CPU time is used there is no further way to speed up DOSBox unless you reduce the load generated by the non-CPU parts of DOSBox.
